    Experienced and energetic Swiss software architect/senior engineer and AWS Certified Solutions Architect with a passion for designing and implementing innovative and state of the art systems in complex business environments. During my work in a Swiss private online bank I’ve taken the lead on and participated in complex projects with strict requirements such as event driven architecture in banking clients onboarding workflows, refactoring of authentication systems, translating business needs into architecture and apis from the design phase to the deployment and maintenance. My soft skills helped me organize and manage meetings with IT, businesses and other teams to improve our collaboration on projects, overall interactions and workflows. I also trained some newcomers to help them quickly understand our business and processes. My experience as an DevOps engineer allow me to see further than the typical developer world and to be independent in setting up, provisioning, templating, configuring, monitoring and maintaining infrastructure, middlewares and deployment and continuous workflows. On the front-end side I’m versed in React/Redux/RxJs to develop modern and reactive, simple and complex web applications. As a freelancer I worked with smaller companies to develop various systems such as a distributed caching engine with distributed rate limiting, a system to stress test different Java frameworks and Redis libraries and some frontend + backend systems to address specific companies needs in various languages using AWS Beanstalk, EC2, Fargate, ... I also have a keen interest and experience in new and interesting technologies and trends such as reactive programming, Kubernetes, algorithmic trading and cryptocurrencies/NFTs as my experience and personal/professional projects on Github demonstrate.
